uP9303 - 5V/12V Synchronous-Rectified Buck Controller

Key Features

  • The uP9303 is a compact synchronous-rectified buck controller specifically designed to operate with single 12V supply voltage and to deliver high quality output voltage. It adopts external compensated, voltage mode control to tightly regulate the feedback voltage to internal 0.6V reference voltage. The switching frequency is programmable from 50kHz to 500kHz, providing an optimal level of integration to reduce size and cost of the power supply. The uP9303 integrates MOSFET drivers that support.
